Perceived Devaluation among a Cohort of Street-Involved Youth in Vancouver,Canada

Background: Perceived devaluation is a barrier to seeking mental and physical health services among people who use illicit drugs. Objective: Assessing the prevalence and correlates of perceived devaluation within a cohort of street-involved youth. Methods: Data were drawn from an open prospective cohort of street-involved youth who use illicit drugs (aged 14–26 at study enrollment) between December 2013 and May 2015 in Vancouver, Canada. Perceived devaluation was measured using an adapted version of Perceived Devaluation and Discrimination scale. Multivariable generalized estimating equations were constructed to examine factors independently associated with high perceived devaluation. Results: Among 411 street-involved youth, 95.1% reported high perceived devaluation at some point during the study period. In a multivariable analysis, youth who reported high perceived devaluation were significantly more likely to engage in: unprotected sex (Adjusted Odds Ratio [AOR]?=?1.56, 95% Confidence Interval 1.03–2.37); heavy alcohol use (AOR = 2.31, 95% CI 1.22–4.36); and daily heroin use (AOR = 2.07, 95% CI 1.16–3.70). Youth who resided in the Downtown Eastside neighborhood were significantly less likely to report high perceived devaluation (AOR = 0.41, 95% CI 0.26–0.65). Conclusions: Perceived devaluation was extremely prevalent among street-involved youth in our sample. We also observed that youth most in need of health and social services were significantly more likely to report high levels of perceived devaluation which may result in a reluctance to seek out key services and supports. These findings highlight the need to implement stigma reduction interventions for vulnerable youth in this setting.     

Binge Drinking and Unsafe Sex: A Study of Narcology Hospital Patients from St. Petersburg,Russia

ABSTRACT

The purpose of this study was to assess the association between binge alcohol use and unprotected sex in Russian substance users. Participants (N = 181) were narcology hospital patients assessed on demographics, alcohol use, risky sex, and sexually transmitted disease/human immunodeficiency virus (STD/HIV) diagnoses. Adjusted generalized estimating equations (GEEs) logistic regression analysis examined the association between binge drinking and same-day unprotected sex across each of the past 30 days, per participant (N = 5430 observations). Participants were age 18 to 55 years, 75% male, and 64% binge drinking. Sex trade was reported by 27%; history of STDs by 43%; and HIV by 15%. One fourth of daily observations included sex; 88% of these involved unprotected sex. Binge drinking was not associated with same-day unprotected sex (adjusted odds ratio [OR_adj] = 1.0, 95% confidence interval [CI] = 0.7–1.4, χ²(1, N = 5219) = 0.01, ns). Findings document substantial HIV/STD risk and prevalence among Russian narcology patients, but no link between binge drinking and unprotected sex in this population, possibly due to very low rates of condom use generally.     

Effects of government registration on unprotected sex amongst female sex workers in Tijuana; Mexico

BackgroundSex work is partially regulated in Tijuana, but little is known of its health effects. A recent behavioural intervention amongst female sex workers (FSWs) decreased incidence of HIV/STIs by 40%. We evaluated effects of sex worker regulation on condom use amongst FSWs randomized to this intervention.MethodsFSWs aged ≥18 years who reported unprotected sex with ≥1 client in the last 2 months and whether they were registered with Tijuana's Municipal Health Department underwent a brief, theory-based behavioural intervention to increase condom use. At baseline and 6 months, women underwent interviews and testing for HIV, syphilis, Chlamydia trachomatis and Neisseria gonorrhoeae. Negative binomial regression was used to determine the effect of registration on numbers of unprotected sex acts and cumulative HIV/STI incidence.ResultsOf 187 women, 83 (44%) were registered. Lack of registration was associated with higher rates of unprotected sex (rate ratio: 1.7, 95% CI: 1.2–2.3), compared to FSWs who were registered, after controlling for potential confounders.ConclusionsRegistration predicted increased condom use amongst FSWs enrolled in a behavioural intervention. Public health programmes designed to improve condom use amongst FSWs may benefit from understanding the impact of existing regulation systems on HIV risk behaviours.     

Lifetime Doctor-Diagnosed Mental Health Conditions and Current Substance Use Among Gay and Bisexual Men Living in Vancouver,Canada

Background: Studies have found that gay, bisexual, and other men who have sex with men (GBM) have higher rates of mental health conditions and substance use than heterosexual men, but are limited by issues of representativeness. Objectives: To determine the prevalence and correlates of mental health disorders among GBM in Metro Vancouver, Canada. Methods: From 2012 to 2014, the Momentum Health Study recruited GBM (≥16 years) via respondent-driven sampling (RDS) to estimate population parameters. Computer-assisted self-interviews (CASI) collected demographic, psychosocial, and behavioral information, while nurse-administered structured interviews asked about mental health diagnoses and treatment. Multivariate logistic regression using manual backward selection was used to identify covariates for any lifetime doctor diagnosed: (1) alcohol/substance use disorder and (2) any other mental health disorder. Results: Of 719 participants, 17.4% reported a substance use disorder and 35.2% reported any other mental health disorder; 24.0% of all GBM were currently receiving treatment. A lifetime substance use disorder diagnosis was negatively associated with being a student (AOR = 0.52, 95% CI [confidence interval]: 0.27–0.99) and an annual income ≥$30,000 CAD (AOR = 0.38, 95% CI: 0.21–0.67) and positively associated with HIV-positive serostatus (AOR = 2.54, 95% CI: 1.63–3.96), recent crystal methamphetamine use (AOR = 2.73, 95% CI: 1.69–4.40) and recent heroin use (AOR = 5.59, 95% CI: 2.39–13.12). Any other lifetime mental health disorder diagnosis was negatively associated with self-identifying as Latin American (AOR = 0.25, 95% CI: 0.08–0.81), being a refugee or visa holder (AOR = 0.18, 95% CI: 0.05–0.65), and living outside Vancouver (AOR = 0.52, 95% CI: 0.33–0.82), and positively associated with abnormal anxiety symptomology scores (AOR = 3.05, 95% CI: 2.06–4.51). Conclusions: Mental health conditions and substance use, which have important implications for clinical and public health practice, were highly prevalent and co-occurring.     

Substance Use among Female Sex Workers in Two US-Mexico Border Cities: Associations with Age of Entry

Background: Research has documented consistent associations between entry into sex work as a minor and sexual HIV risk. However, previous studies have not examined whether substance use and related HIV risk are elevated among those who enter sex work under age 18. Methods: Quantitative data were collected via time-location sampling of 603 female sex workers (FSWs) ages 18?years and older residing in two Mexico-US border cities. Age of entry into sex work (categorized as 15?years or younger, 16–17?years, or 18?years and older) was assessed as a predictor of substance use (forced and voluntary) within the first month post-entry and recent (past 30?days) substance use with clients. Results: Compared to those who entered as adults, participants who entered sex work at age 15 or younger were significantly more likely to report drug use (AOR?=?5.2, CI?=?2.9–8.9) and forced drug use within the first 30?days of entry (AOR= 6.0, CI?=?1.9–18.9), as well as past month drug use with clients (AOR= 3.4, CI?=?1.9–5.8). Similar results were found among participants who entered sex work at age 16–17. Conclusions: Increased risk of recent substance use with clients indicates continuing elevated risk for those entering sex work at these early ages. Early and forced substance use at entry may underlie the elevated risk of HIV infection consistently observed among this population.     

Correlates of Skin and Soft Tissue Infections in Injection Drug Users in a Syringe-Exchange Program in Malmö, Sweden

Background: Injection drug users (IDUs) are at increased risk of various medical conditions, including bacterial skin and soft tissue infections (SSTIs). SSTIs, which are painful and can lead to life-threatening complications, are common but scarcely studied. Objectives: To investigate life time, past 12 month and past 30-day prevalence for SSTI related to injection drug use, in IDUs at Malmö syringe exchange program (Malmö SEP). To investigate factors associated with having ever had an SSTI. Methods: IDUs were recruited from Malmö SEP (N = 80). They participated in a survey with questions about demographics, drug use, and experience of SSTIs. Factors independently associated with self-reported SSTI ever were assessed using logistic regression analysis. Results: The lifetime reported prevalence of SSTI was 58%, past 12 months 30%, and past 30 days 14%. Factors independently associated with SSTI ever were age (adjusted odds ratio [AOR] = 1.09; 95% confidence interval [CI] = 1.01–1.18), female sex (AOR = 6.75; 95% CI = 1.40–32.47), having ever injected prescribed drugs (AOR = 52.15; 95% CI = 5.17–525.67), and having ever injected in the neck (AOR = 8.08; 95% CI = 1.16–56.08). Conclusions/Importance: SSTI is common among IDUs in Malmö. Women and those injecting in the neck or injecting prescribed drugs (crushed tablets/liquids), are more likely to have had an SSTI.     

Parental Style and Its Association With Substance Use in Argentinean Youth

Background: In Europe and the United States, family relationships and parenting behavior can influence youth substance use, but less is known about their influence in Latin American countries. Objective: To explore whether parenting behavior is associated with substance use among Latin American youth. Methods: A cross-sectional, school-based survey of middle-school youth (n = 3172) in three Argentinian cities queried tobacco, alcohol, and drug use using items adapted from global youth surveys. Parenting behavior was assessed with previously validated items that tapped into demandingness and responsiveness, separately for mothers and fathers. Multilevel logistic regression models assessed associations between parenting behavior and substance use after adjusting for student characteristics, socioeconomic indicators, sensation seeking, and smoking amongst peers and family members. Results: Substance use prevalence was 10% for current smoking, 32% for current drinking alcohol, 17% for past 30-day binge drinking (≥5 drinks), and 8% for previous year illicit drug use (marijuana or cocaine). Greater maternal demandingness was independently associated with lower likelihood of current smoking (adjusted odds ratio [AOR] = 0.77; 95% confidence interval (CI): 0.64–0.92), current drinking (AOR = 0.81; 95% CI: 0.71–0.92), binge drinking (AOR = 0.77; 95% CI: 0.66–0.99, and drug use (AOR = 0.71; 95% CI: 0.61–0.83). No other parenting behavior were independently associated with substance use, except for paternal demandingness and binge drinking (AOR = 0.84; 95% CI: 0.74–0.97). For all outcomes, no interactions were found between parenting behavior and student gender. Conclusions: Among Argentine adolescents, maternal demandingness was the strongest and most consistent correlate of substance use, regardless of adolescent substance use behavior or gender.     

Adults who misuse opioids: Substance abuse treatment use and perceived treatment need

Background: Opioid use disorder (OUD) and overdose deaths among the US population continue to increase. This study examined associations of OUD and other substance use disorders with substance abuse treatment use and perceived treatment need among US adults aged 18+ who misused opioids. Methods: The 2015–2016 National Survey on Drug Use and Health provided data (n?=?5100 respondents who misused opioids in the past year). We used multivariable logistic regression models to examine associations of opioid and other substance use disorders with treatment use and perceived treatment need, adjusting for sociodemographic and health statuses. Results: The data showed that 4.7% of adults misused opioids and 19.1% of those who misused had an OUD. Of those with an OUD, only 31.5% had received substance abuse treatment in the past year and 13.6% perceived the need for such treatment. Of those with an OUD, heroin use disorder (adjusted odds ratio [AOR]?=?2.59, 95% confidence interval [CI]?=?1.59–4.23) and having been arrested/booked (AOR?=?1.98, 95% CI?=?1.18–3.33) were associated with higher odds of receiving treatment, whereas lack of health insurance (AOR?=?0.49, 95% CI?=?0.25–0.94) was associated with lower odds. Heroin use disorder (AOR?=?2.16, 95% CI?=?1.23–3.83) and higher mental health impairment scores (AOR?=?1.05, 95% CI?=?1.01–1.09) were associated with higher odds of perceived treatment need. Conclusions: The overall low socioeconomic status and high rates of polysubstance use disorders among those with OUD indicate that they need financial and other help to access treatment and relapse prevention services. The very low rates of perceived treatment need also point to the need for strategies to increase individuals’ recognition of their need for treatment.     

Drug use patterns and associated factors among female sex workers in Iran

ObjectiveThis study examines the prevalence of drug and poly-drug use and their associated factors among female sex workers (FSW) in Iran.MethodsWe analyzed data from a bio-behavioral surveillance survey of 1347 FSW across 13 major cities in Iran in 2015. Two outcome measures were defined: i) past-month “any drug use”, a binary variable defined as none or any; and ii) a three-category past-month “poly-drug use” variable defined as none, only one drug, and more than one drug. Correlates of these two study outcomes were assessed using multivariable logistic regression and multinomial logistic regression, respectively. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were reported.ResultsWe found that 24.9% (95% CI: 16.1, 36.4) and 13.5% (95% CI: 8.1, 21.5) of FSW reported past-month any drug use and poly-drug use, respectively. Longer sex work career (AOR 2.44 [95% CI: 1.28, 4.63]), unstable housing (AOR 2.56 [1.17, 5.64]), past-year experience of sexual violence (AOR 1.61 [1.15, 2.27]), and incarceration (AOR 2.02 [1.23, 3.32]) were positively associated with any drug use. Similarly, FSW who were unstably housed (AOR 3.4 [1.06, 10.95]), reported past-year experience of sexual violence (AOR 2.06 [95% CI: 1.24, 3.41]) and incarceration (AOR 2.82 [1.60, 4.97]) were positively associated with past-month poly-drug use.ConclusionDrug use is frequent among Iranian FSW, particularly among those who experienced sexual violence, unstable housing or incarceration. Programs to reduce harms associated with drug and poly-drug use should target FSW as a priority population.     

Prevalence and Correlates of Any and Frequent Synthetic Cannabinoid Use in a Representative Sample of High School Students

Background: There is increasing evidence that Synthetic Cannabinoid (SC) use is associated with adverse health effects, but little is known about the prevalence of SC use and risk and protective factors for SC use among adolescents. Objectives: To determine the prevalence and correlates of any and frequent SC use in a representative sample of high school students. Methods: The 2013 Youth Risk Behavior Survey was administered to 3,928 high school students in Nevada. A state-added question assessed any and frequent SC use (10 or more times). Weighted logistic regression identified factors for both outcomes. Results: 17.3% of students reported SC use and 4.3% used SCs frequently. As expected, there were strong associations between SC use and other substance use. After controlling for substance use, any SC use was associated with being Hispanic (AOR = 1.74; 95% CI = 1.27, 2.38) and living in a rural county (AOR = 1.68; 95% CI = 1.26, 2.23). Frequent SC use was higher among students who were male (AOR = 2.14; 95% CI = 1.19, 3.84), 18 years of age (AOR = 2.34; 95% CI = 1.18, 4.67), lived in a rural county (AOR = 1.84; 95% CI = 1.11, 3.04), and were offered, sold, or given illegal drugs on school property (AOR = 2.40; 95% CI = 1.53, 3.79). Protective factors for frequent SC use included high parental monitoring (AOR = 0.54; 95% CI = 0.31, 0.93) and sports team participation (AOR = 0.61; 95% CI = 0.37, 0.99). Conclusions/Importance: SC prevention policies and programs should focus on adolescents who live in rural settings and engage in substance use. Initiatives to address drug availability as school and promote parent involvement are also warranted.     

Physical Factors,Personal Characteristics,and Substance Use: Associations With Obesity

ABSTRACT. Background: Because obesity has become a major public health problem, attention to a range of its predictors is needed. This study examined the association of physical factors, personal characteristics, and substance use with obesity in a sample (N = 815) of African American and Puerto Rican young adults with a mean age of 32. Methods: Body mass index (BMI) was calculated to assess obesity. Bivariate and multivariate logistic regression analyses were conducted. Results: Bivariate analyses showed that protective factors such as physical activity (adjusted odds ratio [AOR] = .82, 95% confidence interval [CI] = .74–.91), healthy diet (AOR = .96, 95% CI = .93–.99), self-control (AOR = .93, 95% CI = .87–.98), and life satisfaction (AOR = .97, 95% CI = .95–.99) were associated with a reduced probability of being obese. Marijuana use was also associated with a decreased probability of obesity (AOR = .89, 95% CI = .80–.99), but was not considered a protective factor. Risk factors such as short sleep duration (AOR = 1.70, 95% CI = 1.24–2.33) and depressive mood (AOR = 1.05, 95% CI = 1.01–1.09) were associated with an increased probability of being obese. Conclusions: For African Americans and Puerto Ricans, programs to treat obesity should focus on increasing sleep, physical activity, and life satisfaction.     

Age of Sexual Debut and Cannabis Use in the United States

Background: Understanding the interrelationships between risky health behaviors is critical for health promotion efforts. Conceptual frameworks for understanding substance misuse (e.g. stepping-stone models) have not yet widely incorporated other risky behaviors, including those related to sexual health. Objectives: The goals of this study were to assess the relationship between early sexual debut and cannabis use, examine the role of licit substance use in this association, and evaluate differences by gender and race/ethnicity. Methods: Data came from the National Comorbidity Survey-Replication (NCS-R). Primary analysis was restricted to respondents who reported sexual debut at ≥12 years (n = 5,036). Age at sexual debut was categorized as early (<18 years), average (18 years) and late (>18 years). Logistic regression was used to assess the relationship between age at sexual debut and cannabis use. Interaction terms were used to evaluate effect modification by gender and race/ethnicity. Results: Later age of sexual debut was associated with lower odds of cannabis use relative to the average age of debut (AOR = 0.50, 95% CI = 0.37–0.66). For every year that respondents delayed their sexual debut, the relative odds of lifetime cannabis use declined by 17%. After accounting for alcohol and tobacco use the association between early sexual debut and cannabis was attenuated (AOR = 0.90, 95% CI = 0.68–1.20), while later age of debut remained protective (AOR = 0.57, 95% CI = 0.42–0.78). Results were generally consistent across race/ethnicity and gender. Conclusions: Multifactorial intervention strategies targeting both sexual health and substance use may be warranted.     

Severity of drug dependence, economic pressure and HIV-related risk behaviors among non-institutionalized female injecting drug users who are also sex workers in China

BACKGROUND: Female injecting drug users (IDUs) who are also sex workers (FSW-IDUs) is an important bridge population transmitting HIV from the IDU population to clients of FSWs. Little is known about the relationships between severity of drug dependence, economic pressure and relevant HIV-related risk behaviors. METHODS: 281 non-institutionalized participants were recruited using snowball sampling methods. Anonymous face-to-face interviews were administered by trained doctors. RESULTS: 64.1% of participants used condoms inconsistently with their clients in the past 6 months; 28.5% served at least 2 clients per day and 48.4% practiced at least one of the three studied needle sharing behaviors. Severity of drug dependence (adjusted OR=1.05, p<0.01) and economic pressure (adjusted OR=1.07 to 2.52, p<0.05) were significantly associated with inconsistent condom use with clients in the last 6 months. Severity of drug dependence (adjusted OR=1.15, p<0.01) and variables related to perceived economic pressure (adjusted OR=1.09-3.05, p<0.05) were significantly associated with higher frequency of commercial sex transaction. Severity of drug dependence (adjusted OR=1.07, p<0.01) were also associated with needle sharing behaviors. In summary models, severity of drug dependence (OR=1.17, p<0.001), economic pressure (OR=1.39, p<0.001) and their interaction term (OR=0.98, p<0.001) were all associated with inconsistent condom use with clients in the last 6 months. CONCLUSIONS: Prevalence of unprotected commercial sex was high and was independently associated with severity of drug dependence and economic pressure; severity of drug dependence was also associated with needle sharing behaviors. Such issues need to be fully considered when planning research studies and interventions.     

Socioecological Factors Related to Hazardous Alcohol use among Female Sex Workers in Lilongwe,Malawi: A Mixed Methods Study

Background: Alcohol use is pervasive among female sex workers (FSW) placing them at increased risk of violence and sexual risk behaviors. FSW often live and work where alcohol is highly normative. Objective: To understand the socioecological influences on hazardous alcohol use among FSW in Malawi. Methods: In 2014, 200 FSW identified through venue-based sampling in Lilongwe, Malawi, completed a quantitative behavioral survey, with a sub-sample participating in qualitative interviews. Multivariable log-binomial regression was used to identify associations between hazardous alcohol use (AUDIT score ≥ 7) and time in sex work, clients per week, unprotected sex, alcohol use with clients, and living environment. Qualitative interviews enhanced findings from quantitative data and identify emergent themes around socioecological influences on alcohol use. Results: Over 50% reported hazardous alcohol use and lived in an alcohol-serving venue. Hazardous alcohol use was associated with sex work duration of ≥2 years (aPR: 1.30; 95%CI: 1.02,1.65) and alcohol use at last sex with a client (aPR: 1.29; 95%CI: 1.06,1.57). FSW perceived alcohol as a facilitator for sex work by reducing inhibitions and attracting clients, but acknowledged alcohol leads to violence and/or unprotected sex. Despite these risks and a motivation to reduce use, FSW feared that refusing to drink would be tantamount to turning away clients. Conclusions: Although FSW recognized alcohol-related risks, the norms and power dynamics of sex work perpetuated hazardous alcohol use. Multilevel interventions are needed to collectively change norms around drinking and sex work that will enable FSW to reduce alcohol consumption when engaging in their work.     

HIV and HCV Prevalence and Gender-Specific Risk Profiles of Crack Cocaine Smokers and Dual Users of Injection Drugs

The present analysis compares HIV and HCV prevalence and associated gender-specific risk patterns of dual users (i.e., crack smokers who inject drugs) and never injectors. Two logistic models, one restricted to female and the other to male crack smokers, were constructed to identify gender-specific risk factors associated with dual use (p < 0.05). Of 437 crack smokers, 246 (56%) were dual users while 191 (44%) were never injectors. In a fitted logistic regression model, dual use among female crack smokers was associated with HCV infection (adjusted OR = 4.65, 95% CI: 1.92–9.70), exchanging sex for money, drugs, or shelter while using crack (aOR = 4.47, 95% CI: 1.56–12.80), having a casual partner who injects (aOR = 4.13, 95% CI: 1.05–16.26), having equipment broken or confiscated by police without being arrested (aOR = 3.66, 95% CI: 1.43–9.34), and HIV infection (aOR = 2.07, 95% CI: 1.18–5.96). Among male crack smokers, dual use was associated with HCV infection (aOR = 5.34, 95% CI: 2.10–13.18), exchanging sex for money, drugs, or shelter (aOR = 3.25, 95% CI: 1.59–6.65), crack use history ≥ 5 years (aOR = 2.16, 95% CI: 1.29–3.63), and smoking in a group of unknown people (such as crack houses, alleys; aOR = 1.70, 95% CI: 1.10–2.81). These findings highlight the need for evidence-based prevention and harm reduction initiatives that directly targeting crack cocaine smokers, with particular attention given to female dual users of injection drugs.     

The Role of Pregnancy Concerns in the Relationship between Substance Use and Unprotected Sex among Adolescents

Background: Substance use and unprotected sex are prevalent among adolescents. The link between substance use and unprotected sex is well-established. Research has also highlighted how adolescents’ attitudes and risk perceptions regarding unprotected sex, including concerns about pregnancy (“Getting pregnant would force me to grow up too fast”), are associated with unprotected sex and unplanned pregnancy. However, less research has examined the potential relationship between pregnancy concerns and substance use among adolescents. Objectives: The study prospectively examined (1) differences in pregnancy concerns across patterns of substance use and (2) whether pregnancy concerns mediate the relationship between substance use and later unprotected sex among a sample of middle and high school students. Method: 98 adolescents [M(SD) age = 14.28(1.68), 59.4% female, 59.4% black/African American] completed self-report measures of marijuana and alcohol use, pregnancy concerns, and unprotected sex across three time points over 6?months (T1–T3). Results: Substance users (alcohol/marijuana) reported fewer pregnancy concerns compared to non-substance users (t?=?2.99, p = .04). Pregnancy concerns at T2 mediated the relationship between T1 lifetime substance use and later unprotected sex (T3) (indirect effect: b?=?0.10, CI[.01–.41]; direct effect: b?=?0.15, p = .32), controlling for gender, age, and race. More frequent substance use (T1) was related to fewer pregnancy concerns at T2 (b = ?0.10, p = .04); fewer pregnancy concerns were related to increased likelihood of later unprotected sex (b = ?1.02, p = .02). Conclusions: Findings offer new insight into associations between substance use and unprotected sex and suggest that substance use and sexual health interventions should target pregnancy concerns.     

Factors associated with employment among a cohort of injection drug users

Introduction and Aims. One of the most substantial costs of drug use is lost productivity and social functioning, including holding of a regular job. However, little is known about employment patterns of injection drug users (IDU). We sought to identify factors that were associated with legal employment among IDU. Design and Methods. We describe the employment patterns of participants of a longitudinal cohort study of IDU in Vancouver, Canada. We then use generalised estimating equations (GEE) to determine statistical associations between legal employment and various intrinsic, acquired, behavioural and circumstantial factors. Results. From 1 June 1999 to 30 November 2003, 330 (27.7%) of 1190 participants reported having a job at some point during follow up. Employment rates remain somewhat stable throughout the study period (9–12.4%). Factors positively and significantly associated with legal employment in multivariate analysis were male gender (adjusted odds ratio [AOR] = 2.78) and living outside the Downtown Eastside (AOR = 1.85). Factors negatively and significantly associated with legal employment included older age (AOR = 0.97); Aboriginal ethnicity (AOR = 0.72); HIV‐positive serostatus (AOR = 0.32); HCV‐positive serostatus (AOR = 0.46); daily heroin injection (AOR = 0.73); daily crack use (AOR = 0.77); public injecting (AOR = 0.50); sex trade involvement (AOR = 0.49); recent incarceration (AOR = 0.56); and unstable housing (AOR = 0.57). Discussion and Conclusions. Our results suggest a stabilising effect of employment for IDU and socio‐demographic, drug use and risk‐related barriers to employment. There is a strong case to address these barriers and to develop innovative employment programming for high‐risk drug users.[Richardson L, Wood E, Li K, Kerr T.

Predictors of Illicit Drug Use Among Prisoners

Background: The United States of America currently has the highest incarceration rate in the world, and approximately 80% of incarcerated individuals have a history of illicit drug use. Despite institutional prohibitions, drug use continues in prison, and is associated with a range of negative outcomes. Objectives: To assess the relationship between prison drug use, duration of incarceration, and a range of covariates. Results: Most participants self-reported a history of illicit drug use (77.5%). Seven percent reportedly used drugs during the previous six months of incarceration (n = 100). Participants who had been incarcerated for more than a year were less likely than those incarcerated for longer than a year to report using drugs (OR = 0.50; 95% CI = 0.26–0.98). Participants aged 37–89 were less likely than younger prisoners to use drugs (OR = 0.39; 95% CI = 0.19–0.80). Heroin users were twice as likely as nonheroin users to use drugs (OR = 2.28; 95% CI = 1.04–5.03); crack cocaine users were also twice as likely as participants with no history of crack cocaine usage to report drug use (OR = 2.53; 95% CI = 1.13–5.69). Conclusions: Correctional institutions should be used as a resource to offer evidence-based services to curb drug usage. Drug treatment programs for younger prisoners, heroin and crack cocaine users, and at the beginning of a prisoner's sentence should be considered for this population.
